my experience with my blog

[alec11]

I got around 40 comment everyday on my blog, and all of them are spam comment
I wonder if I can stop them.

I think you can try using some external comment posting scripts that allow you to delete unnessary spam comments or allow only registered reader to post into your blog. Anyway, some people like to post comment to advertise their own blog / site, we can't really block them all.

well, we can do that too (promote by giving comment on other blog)
It's an effective way to increase PR
